Quick Circulating Coin Facts:

Mutilated Coins:
United States Coins no longer fit for circulation are classified as "uncurrent" or mutilated.

Uncurrent coins are coins that are worn yet recognizable as to genuineness and denomination, and are machine countable.
Uncurrent coins are redeemed by the Federal Reserve Banks, then forwarded to the Mint for disposition.

Mutilated coins are coins that are chipped, fused and not machine countable.
Mutilated coins are only redeemable through the United States Philadelphia Mint facility.

All uncurrent or mutilated coins received by the Mint are melted and reused in the manufacture of coinage strips.
